Introduction to Q235NH Weather Resistant Board
Q235NH weathering steel, which is atmospheric corrosion-resistant steel, is developed from ordinary carbon steel with a small amount of copper, chromium and other corrosion-resistant elements added. It has the strength, plastic extension, forming, welding and cutting, abrasion, high temperature, etc. of high-quality steel. Fatigue resistance and other characteristics, the weather resistance is 2 to 8 times that of ordinary carbon steel, and the paintability is 1.5 to 10 times that of ordinary carbon steel. At the same time, its rust-resistant characteristics enable components to resist corrosion, extend service life, and reduce thickness and consumption. And save labor and energy.
Q235NH weathering plates include Q235NHA, Q235NHB, Q235NHC, Q235NHD, Q235NHE steel plates, Q295NHA weathering steel, which belongs to welded weathering steel and is also called atmospheric corrosion-resistant steel. Q235NHA, Q235NHB, Q235NHC, Q235NHD, Q235NHE can be produced by Wuyang Steel Plant , Q is the alphabet of the Chinese pinyin for "Qiang" in yield strength, 235 is the lower limit of the lower yield strength of steel, in N/mm²; NH is the alphabet of the Chinese Pinyin for weather resistance, and A is the quality grade. Q235NHA, Q235NHB, Q235NHC, Q235NHD, Q235NHE are used for structural purposes such as vehicles, containers, buildings, bridges or other structural parts. Compared with high weathering steel, they have better welding performance. Q235NHA, Q235NHB, Q235NHC, Q235NHD, Q235NHE Wugang futures are fixed rolled, with fast delivery time and good quality.
Q235NHA, Q235NHB, Q235NHC, Q235NHD, Q235NHE steel plate grade naming: Q-yield strength, 235 yield strength value, unit: MPa, NH-weather resistance, A, B, C, D, E quality grades.
Q235NH is widely used in: containers, power plant chimneys, railway projects and other outdoor steel, such as steel for large outdoor sculptures. Weathering steel (that is, atmospheric corrosion-resistant steel) is between ordinary steel and stainless steel. The low-alloy steel series, which is cheap and high-quality, has achieved sustainable development and innovation after incorporating new mechanisms, new technologies and new processes in modern metallurgy. It is one of the series of steel types at the forefront of the world's super steel technology. Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements added. It has the characteristics of high-quality steel such as strength, plasticity, shaping, welding and cutting, abrasion, high temperature, fatigue, etc.; its weather resistance is 2~ that of ordinary carbon steel. 8 times, and the paintability is 1.5~10 times that of ordinary carbon steel. It can be used in thinner form, exposed or simplified painting.
